You have to evaluate the cost of failure vs the cost of calibration. I am sure many have seen this already but this is a great Navy video on the importance of calibration http://www.youtube.com/watch?v=yxZBNYBoLLU Best regards, Benjamin Sheena IET Labs --- In GenRad@yahoogroups.com, Roy Morgan <k1lky@...> wrote: > > > On Jun 6, 2012, at 4:10 PM, jackinnj wrote: > > > > > Nope, Thaler Corporation -- used to be in Tucson AZ -- they produced the VRE105 Precision Reference. > > > > Thaler Corp > 2015 N Forbes Blvd > Tucson AZ 85745-1458 > > Tel: 520-882-4000 > > The design and performance of a precision voltage reference ... > <http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=slyt168&fileType=pdf&track=no > > > By Perry Miller, Application Specialist—Data Converters, Texas > Instruments, Dallas and Doug Moore, Managing Director, Thaler Corp., Tucson, Arizona ... > > "The first paper on this topic appeared in the November > 1999 issue of Analog Applications Journal > (www-s.ti.com/sc/techlit/slyt183).
